3.6.4 LEARN 
 
LEARN adapts the PID controller of the valve to the vacuum system and its operating conditions. LEARN must be 
executed only once during system setup. 
The LEARN routine determines the characteristic of the vacuum system. Based on this, the PID controller is able to run 
fast and accurate pressure control cycles. 
This characteristic depends on various parameters such as chamber volume, conductance and flow regime. Therefore it 
must be performed with a specific gas flow according to instruction below. 
The result of LEARN is a pressure versus valve position data table. This table is used to adapt the PID parameters. The 
data table is stored in the device memory which is power fail save. The data table can be up-/downloaded via ‘Control 
Performance Analyzer’ software or remote interface. Due to encoding the data may not be interpreted directly. 
By an OPEN VALVE, CLOSE VALVE, POSITION CONTROL or PRESSURE CONTROL command the routine will be 
interrupted. 
 

Local operation

: 

(‘Control View’, ‘Control Performance Analyzer’ or 

‘Service Box 2‘) 

Remote operation

: 

(Refer to chapter «RS232 control commands» resp. 

«RS232 setup commands» for details) 

1. Send 

OPEN 

VALVE 

2.  Set specific gas flow according to calculation 

below and wait until flow is stable. 
LEARN does not need to be performed with the 
process gas. Instead N

2

 or Ar may be used. 

Go to ‘Learn / LEARN’ menu and follow instructions. 

 
Note: Gasflow calculation according to 
recommendation below is done automatically based 
on inputs. 

3. Send 

LEARN 

(with pressure limit set to full scale) 

 
 
Note:  Sensor signal must not shift during LEARN. Wait until sensor signal is stable before LEARN is performed. 
 
Note:  Learn may take several minutes. Do not interrupt the routine as a single full run is required to ensure fast and 

accurate pressure control. The PID controller covers 5% to 5000% of the gas flow which was used for learn.
